PROVIDENCE, R.I. — Neighbors of The Breakers estate, the Gilded Age Vanderbilt family mansion and national historic landmark in Newport, are suing to block a new welcome center that's planned for the site.

The neighborhood association filed the lawsuit Friday against the Preservation Society of Newport County, which owns the 70-room mansion and operates it as a museum. The Preservation Society wants to build the center for its 400,000 annual visitors with services including ticketing and prepared sandwiches.
